Parallel Planes In Geometry: Definition And Examples.

Parallel planes

planes that never intersect

Parallel planes are two or more planes that do not intersect each other no matter how far they are extended in all directions. In other words, parallel planes are two or more coplanar planes that never meet or cross each other.

When we talk about planes in geometry, we are talking about two-dimensional surfaces that extend infinitely in all directions. For two planes to be parallel, they must be equidistant from each other at all points. This means that if we were to draw a perpendicular line from one plane to the other, the perpendicular line would have the same length at every point along it.

It is worth noting that parallel planes have the same slope or inclination but different y-intercepts. They are often represented in slope-intercept form as y = mx + b, where m is the slope and b is the y-intercept.

Example:

Consider two planes P1 and P2, given by the equations:
P1: 2x + 4y – z = 7
P2: 2x + 4y – z = -3

We can see that the two planes have the same slope or inclination, which is given by the coefficients of x, y, and z. That is, the slope is (2, 4, -1). However, the two planes have different y-intercepts, which are given by the constant terms. Therefore, we can conclude that the two planes P1 and P2 are parallel to each other.
